Imagine yourself trapped up in space, with no way out. No one to protect you. Just a swarm of alien beings who willed themselves into being by way of the corpses of your friends and family. Yeah. That's Dead Space. The entire world is in danger if you can't quell the threat, and the only way to stop these beasts is to cut off their limbs. So not only do you have to be deadly, but you have to be accurate.
